The use of information technology in the design of chippers for the production of technological chips

Abstract

Currently, there is an acute problem of reducing the harmful effects of humans on the environment, the introduction of resource-saving technologies that allow the maximum use of natural raw materials with a minimum percentage of waste. In the production of products at wood working and sawmill enterprises, a large amount of wood waste is generated that requires either disposal or use for the production of wood chips and shavings used in the production of chipboard, OSB boards, fuel briquettes and pellets. Processing of wood waste is carried out in various chippers of a stationary and mobile type, while it must be taken into account that a large amount of wood waste is generated in cutting areas, lower warehouses of enterprises, therefore, mobile chippers must be used for their processing. Given that the diameter of the chipping disc can exceed 1000 mm at a speed of up to 1500 rpm, during the operation of the chipper, significant loads on the working tool and vibration occur, which can lead to its failure. Vibration during the operation of the chipper can be the result of both design errors and occur when the cutting knives are blunt.
